Abstract: A motor assembly includes a single phase motor and a friction clutch. The single phase motor includes a stator and a rotor. The friction clutch includes a pressing member rotating with the rotor, and a connecting member to be connected to a load. wherein when the pressing member rotates, the pressing member generates an axial or radial movement to thereby exert a pressing force to the connecting member to cause the connecting member to rotate due to a frictional force generated between the pressing member and the connecting member. The present invention further provides a fluid driving device incorporating the motor assembly.

Abstract: A single-phase outer-rotor motor includes a stator and a rotor surrounding the stator. The stator and rotor define therebetween an even gap. The stator includes a stator core. The stator core includes a yoke and a plurality of teeth. Each tooth includes a tooth body and a tooth tip. A winding slot formed between each two adjacent tooth bodys. Windings are wound around the tooth bodys. The tooth tip forms an outer circumferential surface facing the rotor. The outer circumferential surfaces of all the tooth tips are connected to each other to collectively form a substantial cylindrical surface. The outer circumferential surface of the tooth tip is formed with a positioning groove deviating from a center of the outer circumferential surface of the tooth tip, which prevents the rotor from stopping at the dead-point position and hence ensures that the rotor can be successfully started when the motor is energized.

Abstract: A PMDC motor has a housing, a stator magnet disposed in an interior of the housing, and a rotor core disposed within the stator magnet. A ratio of an outer diameter of the rotor core to the outer diameter of the housing is from 0.60 to 0.67. The noise of the motor during operation is reduced by increasing the thickness of the stator magnet, reducing the outer diameter of the rotor core, reducing the air gap between the magnet and the rotor core and reducing the rotational inertia of the rotor core. The motor is particularly suited for use in vehicle HVAC systems where low noise is an important requirement.
